Struct PatternStruct

pub struct PatternStruct {
    pub concrete_struct_id: ConcreteStructId,
    pub field_patterns: Vec<(Member, PatternId)>,
    pub ty: TypeId,
    pub n_snapshots: usize,
    pub stable_ptr: PatternStructPtr,
}

A pattern that destructures a struct to its fields.

Fields

concrete_struct_id: ConcreteStructId

field_patterns: Vec<(Member, PatternId)>

ty: TypeId

n_snapshots: usize

stable_ptr: PatternStructPtr

Trait Implementations

impl Clone for PatternStruct

fn clone(&self) -> PatternStruct

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PatternStruct

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a, T: ?Sized + Upcast<ExprFormatter<'a>>> DebugWithDb<T> for PatternStruct

fn fmt(&self, f: &mut Formatter<'_>, other_db: &T) -> Result

fn debug<'me, 'db>(&'me self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

fn into_debug<'me, 'db>(self, db: &'me Db) -> DebugWith<'me, Db>

where Self: Sized + 'me,

impl PartialEq for PatternStruct

fn eq(&self, other: &PatternStruct) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
